The processing tool of the large synchronous motor armature spindle herringbone magnet steel mounting groove of the utility model, in processing,
The confirmation of machining locus: when the longitudinal center line of armature spindle and the X-axis of planer-type milling machine are parallel, we are fixed for the placement state of this axis
Justice is that axis is directly put.The angle of the longitudinal center line of the center line and axis of tapered plane on armature spindle is 3.13 °, at this point, armature spindle
The center line of two sides tapered plane is respectively 3.13 ° with the X-axis angle of planer-type milling machine, then, process tapered plane and magnet steel mounting groove
When, the cutter track that must move diagonally along X, Y-axis could complete the processing of tapered plane and slot, and this processing method must use gantry
The advantages of milling machine X, Y-axis linkage motion cutting, this processing method: clamping is simple；It is convenient to tune up；Clamped one time processing；Operation is opposite
It is easier；Machining accuracy is high；Process-cycle is short.The shortcomings that this processing method: numerically-controlled machine tool need to be used；Program composition is multiple
It is miscellaneous；It is complicated to process tool track；Operation difficulty is big.
The processing tool of the large synchronous motor armature spindle herringbone magnet steel mounting groove of the utility model, planer-type milling machine exist
The top processing herringbone plane and slot of magnetic yoke increase magnetic in the radially opposite sides (two sides symmetric position) of central hollow magnetic yoke 102
Yoke support device improves the intensity of magnetic yoke, vibrates when magnetic yoke being avoided to process, and floor-type milling & boring machine top is similar to when processing in this way
Portion processes herringbone plane and dovetail slot.Since the main shaft 50 of planer-type milling machine is mounted on crossbeam 40, crossbeam 40 can be neatly
It moves up and down, same main shaft 50 also can be neatly moved forward and backward on crossbeam 40, and 50 extension elongation of main shaft, which can according to need, appoints
The rigidity of meaning adjustment, main shaft 50 is good, and cutter is hardly damaged, and the roughness of dimensional tolerance and machined surface can be guaranteed.Therefore,
The shortcomings that top processing herringbone plane and slot scheme of magnetic yoke can be efficiently used, this scheme is machined surface from workbench
Face is relatively high, and the labor intensity of operator can effectively solve metalworking problem than increasing.Armature spindle in rotary index,
The left side non-shaft stretching end hollow shaft 101 of armature spindle can only rotate in the axis hole of the slipper bracket of Left-side support mechanism 1, right-hand axis
Stretching end hollow shaft 103 can only rotate in the axis hole of the slipper bracket of Right side support mechanism 2, in this way, can reduce and limit whole
The bias of a armature spindle, and, it is not easy to the outer surface for wearing armature spindle makes the armature spindle finished product of processing meet use and wants
It asks.
The processing tool of the large synchronous motor armature spindle herringbone magnet steel mounting groove of the utility model, it is specific to work
Process are as follows:
(1) armature spindle tunes up step: when processing herringbone magnet steel mounting groove, we must adjust armature spindle first
Whole, the longitudinal center line of this processing scheme armature spindle and the X-axis of planer-type milling machine are parallel, this is very for the state for adjusting axis
Advantageous, the Up Highway UHW and side bus that need to only adjust axis bearings at both ends shelves outer circle can adjust the center line and planer-type milling machine of axis
The X-axis depth of parallelism, the technical requirements depth of parallelism≤0.02mm.Concrete operations are that dial gauge is mounted on the main shaft of lathe, percentage
Table measuring head is against on the Up Highway UHW of bearing guard outer circle, reads percentage meter reading, and record reading, dial gauge is along X, by a side axle
It holds shelves and is moved to other side bearing guard, keep the coordinate of Y-axis and Z axis constant, read percentage meter reading, compare the reading of two sides dial gauge
Number, such as difference > 0.02mm, then adjusts the gasket below bracket, until two sides dial gauge reads difference≤0.02mm.With
Same method measures side bus, reads axis two sides bearing guard percentage meter reading, compares two sides percentage meter reading, such as difference >
0.02mm then adjusts bracket front-rear position, until two sides dial gauge reads difference≤0.02mm, completes armature spindle and tunes up；
(2) rotary encoder installation steps: in the left side mounting tool branch of the left side non-shaft stretching end hollow shaft of armature spindle
Frame, together with the axis connection of the rotary encoder of 1.8 ten thousand lines, the stator of rotary encoder is fixed on cushion block tooling bracket,
For shaft circumference etc. point control.When installation, it can be filled by the support bracket fastened adjusting on the outside of the stator of adjusting rotary encoder
It sets to adjust the concentricity of the axis of rotary encoder and armature spindle, rotary encoder precision can reach 1/1000 °, and halving precision is full
Sufficient technical requirements；
(3) armature spindle rotate angle set-up procedure: for realize shaft rotate angle fine tuning, within the barrel between position, in advance
First circumference uniform distribution processing screw hole, is screwed into bolt in screw hole, is finely adjusted using jack pair armature spindle rotation angle；
(4) armature spindle fixing step: after the circumferential angle of armature spindle is adjusted, needing armature spindle to fix could be into
Row machining.Slipper bracket 12 is fixed with bolt first, since the lock ability of slipper bracket 12 is limited, this is fixed,
Processing tapered plane and armature spindle is easy rotation displacement during dovetail slot, therefore, for prevent it is such happen, using
After axis rotation angle fine-adjustment mechanism adjusts armature spindle rotation angle, jack 61 is not taken away, moreover, in armature spindle
Between the radially opposite sides of hollow magnetic yoke 102 respectively put a jack 61 and withstand bolt, avoid the axis in processing from rolling.Due in
Between hollow magnetic yoke 102 be cylinder, wall is thin, and magnetic yoke can be vibrated when processing, and cutter is easy to damage, the dimensional accuracy of machined surface and
Surface roughness is difficult to control.Therefore, side increases front side supporting mechanism correspondingly before and after central hollow magnetic yoke 102
3 and Backside support mechanism 4.
(5) selection and procedure of processing of cutter, rotor rim surface need to successively process 28 groups of lambdoid tapered planes and peace
The dovetail slot of magnet steel is filled, dovetail slot is on the basis of tapered plane, therefore, it is necessary to which first then processing tapered plane reprocesses dovetail
Slot, two right-angle side of tapered plane is arc transition, cannot be processed with general plain milling cutter, and practical we use 63 maize milling cutter of Φ
Herringbone tapered plane is processed in a manner of the linkage of XY axis, periphery uses the slotting cutter of Φ 20 to process again, guarantees herringbone inclined-plane R10 circle
Angle, both sides symmetrical machining.Two plane symmetries of tapered plane to the distance of longitudinal center line and 180 ° of distributions are by magnetic yoke two
For the technique seam allowance at end come what is realized, technique seam allowance outer circle is the simultaneous processing in axis Vehicle Processing, therefore, technique seam allowance outer circle with
What the center line concentricity of axis was guaranteed by lathe, technique seam allowance outside diameter size is equal to the spacing of two tapered planes of 180 ° of distributions
Size, as long as controlling tapered plane and technique seam allowance outer circle is tangent, it is ensured that tapered plane to longitudinal center line distance and
Two plane symmetries of 180 ° of distributions.Two dovetail slots will be processed on each tapered plane, dovetail slot itself is by dimensional tolerance, angle
The relative position tolerance of tolerance and two bar grooves first processes dovetail slot straight trough using the slotting cutter of Φ 25, then reuses us
The form cutter of customization processes dovetail slot, and form cutter is adapted with the size for the dovetail slot for meeting design requirement, using forming
Processing quality can be improved in the benefit one of milling cutter processing dovetail slot, and two can be improved working efficiency, and three can reduce labor intensity.
(6) measuring process of herringbone magnet steel mounting groove: general using three kinds of measurement snap-gauge inspections after dovetail slot processes
Check of foundation subsoil form quality amount, is flute profile snap-gauge, spacing dimension snap-gauges on the inside of spacing dimension snap-gauge and two slots on the outside of two slots respectively, every kind
Snap-gauge is all only logical snap-gauge.Single dovetail flute profile dimensional tolerance is measured with flute profile snap-gauge；With spacing dimension snap-gauge on the outside of two slots
Measuring flume spacing dimension tolerance is distinguished with spacing dimension snap-gauge on the inside of two slots；Because two dovetail slots on tapered plane are for pacifying
Magnet steel is filled, therefore, light is examined not enough with snap-gauge, also needs the processing quality that dovetail slot is examined with magnet steel, and magnet steel can be smoothly
Dovetail slot is put into as qualification.
28 groups of herringbone tapered planes and magnet steel mounting groove are processed in the magnetic yoke of armature spindle, are the key that entire axis processing skills
The quality of art, tapered plane and the processing of magnet steel mounting groove is high, smoothly installs and creates favorable conditions for the magnet steel in later period, the utility model
Large synchronous motor armature spindle herringbone magnet steel mounting groove processing tool, both can solve herringbone tapered plane and magnet steel peace
Tankage processing problems and reduction processing cost, and can be shortened the production cycle, working efficiency is improved, specifically according to scheduled technique side
The tapered plane and slot of case processing, actual processing effect is very good, satisfactory rotor herringbone tapered plane and the magnet steel mounting groove completed
Processing tasks.
In conclusion the processing tool of the large synchronous motor armature spindle herringbone magnet steel mounting groove of the utility model,
May be implemented armature spindle can continuous and stable rotation, accurate equal part and reliable location, guarantee armature spindle equal indicative and dimensioning
Very little precision completes the processing of herringbone plane and magnet steel mounting groove on armature spindle.
